On Wednesday evening, Celtic’s final January signing, Hyeongyu Oh, received a warm welcome as he made his first appearance at Parkhead.
The 21-year-old was the fourth signing made by Ange Postecoglou in the winter market as he strengthened his squad for the second half of the campaign.
Celtic supporters were given their first glimpse of the South Korean international last Sunday, coming off the bench against Dundee United.

The striker was given an eight-minute cameo as he aims to build up his match sharpness, having not played a competitive fixture since October.
The Celtic manager appears to be gradually building up Oh’s minutes off the bench, and against Livingston, he was handed his first 15 minutes at Paradise.
This weekend’s visit to take on St Johnstone is likely going to be another good opportunity for more minutes as a substitute.
Some might ask whether Postecoglou will consider switching his strikers for this game on what is going to be a difficult surface.
However, in my opinion, it seems unlikely that the 57-year-old would take Kyogo Furuhashi out of the side, having scored against Livi on Wednesday.
So, when might be the best opportunity for Ange Postecoglou to hand Hyeongyu Oh his full Celtic debut?

Upcoming Scottish Cup clash vs St Mirren seems like ideal opportunity for Oh’s full Celtic debut.
Looking at the fixture list, the best opportunity is likely going to be the upcoming Scottish Cup tie against St Mirren at Celtic Park.
The Bhoys were drawn to take on Stephen Robinson’s side at home on Saturday 11th March.
Although Ange Postecoglou has showcased that he will play his strongest teams in the cup competitions, it still feels like the best chance to hand our fourth signing of last month his first Celtic start.
Oh could prove to be a big player in the second half of the campaign. So you would imagine the Celtic boss is keen to get minutes into his legs as soon as possible.
Of course, that will include his appearances on the bench over the next few weeks, and he will also be looking to get off the mark in front of goal.
I am sure Ange Postecoglou and his coaching staff will already have plans in place regarding when they are hoping to hand Oh his full debut.
In my opinion, that seems most likely to come against St Mirren in the Scottish Cup next weekend.
